Just thought i would share this with those of you who may me interested...
Just purchased a "Greenspeed scrub pad" to use for agitating my presprays.
Just tried it out on a white polyprop carpet with light soil and it works a treat compared to a standard microfibre bonnet.
The stripes you see are nylon and help to give the pad a bit more ooommph and they do lift the pile.
I finished the carpet off with a standard microfibre pad... im impressed
